The Festool 202392 BSTA HS D 4 L60 CE Drill Countersink is a Festool drill countersink built for repetitive drilling and countersinking in decking and patio flooring applications. This is a drill countersink designed for drilling and countersinking wood in one step. Model Number: 202392. If you are laying deck boards or working on substructures and want cleaner results with less tool swapping, this accessory is made for exactly that job.

The main advantage here is simple: one operation instead of two. Instead of drilling a pilot hole and then switching to a separate countersink, this tool handles both at once. That matters when you are installing a lot of screws in terrace boards or substructure material, because saved seconds add up fast over a full day. Festool also gives you an adjustable depth stop, so you can dial in the hole depth for different materials and screw head requirements.

Festool rates the maximum drill depth at 2-3/8 inches and the drill diameter at 3/16 inch, which makes this a focused accessory for precise wood fastening work rather than a general-purpose twist bit. The 3/16" (4 mm) size is well suited to controlled pilot and countersink work where consistency matters more than brute force. On deck and patio jobs, that means neater screw seating and less rework.

The construction is another reason this accessory stands out. Festool specifies a carbide drill with adjustable depth stop for precise drilling and countersinking, and also notes that the bit is made from high-quality HSS Bohler steel for long service life. In plain terms, this is built to hold up to repetitive use, and when the bit eventually wears, it can be replaced instead of throwing the whole setup away.

The CENTROTEC interface is a big part of why this accessory feels purpose-built for Festool users. It is suitable for Festool cordless drills with the CENTROTEC interface for use in the WH-CE CENTROTEC tool chuck. Festool calls out the centered, ball-bearing-supported fit as a benefit for optimized power transmission and precision. That is the kind of detail that matters when you are trying to keep hole placement and countersink depth uniform across visible finish surfaces like deck boards.

Jobsite practicality is baked into the design too. The adjustable depth stop is especially designed for machining patio flooring, and the free-rotating style depth stop helps avoid scuffing or damaging the wood surface while you work. That is useful on exposed boards where a small mark around the screw hole is going to be visible after the job is done.

This accessory makes the most sense for deck builders, remodelers, carpenters, and serious DIY users already working in the Festool system. If you own a Festool cordless drill with CENTROTEC and spend real time installing deck planks, terrace flooring, or similar wood surfaces, this is the kind of accessory that earns its keep by making the process faster and more repeatable. If you are not on the CENTROTEC platform, this is not the right fit, because compatibility is one of its core strengths.
